Vaer, the American watchmaker known for its commitment to functional durability and American craftsmanship, has teamed up with Outerknown to launch the limited-edition D4 Solar Diver. The D4 is for those seeking a dependable ocean-oriented tool watch that can also be dressed up for more formal occasions. The perpetual timekeeping function of a solar-powered quartz watch makes it the perfect fit for an everyday wearer. We developed this color combination specifically for this collaboration with exclusive co-branding in multiple areas – face, crown, and engraved on back.

"This unique collaboration marries Vaer’s technical expertise in adventure-ready timepieces with Outerknown’s dedication to mindful design, resulting in a watch that seamlessly transitions from ocean to city while embodying both brands’ commitment to nature and responsible craftsmanship. 

As a D4 model, this watch is solar-powered. In our opinion, the solar movement provides the best of both worlds - perpetual timekeeping with incredible accuracy. Six hours of sunlight will provide six months of power reserve, and the watch can run off any light source (even candlelight).

The perpetual timekeeping function of a solar-powered quartz watch makes it the perfect fit for an everyday wearer, and the choice of 42mm case sizing provides an option for most men's wrists while also maintaining our commitment to ergonomic, and timeless proportions. To further enhance the and functionality of the watch, every D4 comes standard with two interchangeable straps.
